@Moen/to@ Wei fames UNITED STATES PATENT FRED E. HOLMES, OF DETROIT,MICHIGAN.

LAMP.

Application filed March 26, 1917.

To all whom it may concern.'

Be it known that I, Furio E, HOLMES, a citizen ot' the United States ofAmerica, residing at Detroit1 in the Vcounty of Wayne and State ofMichigan, have invented cer tain new and useful. ln'iprovements inLamps, of which the following is a specilication, reference being hadtherein to the accompanying drawings.

This invention relates to automobile lamps or the like and refers moreparticularly to a new and improved construction adapted for use as aheadlight or the like.

Among' the objects ot' the invention are to provide means whereby therays of the light can he thrown downward or to other positions dillcrentfromfthe normal; to utilize the shitting ot' the reflector and the bulbor other source of light for this purpose; to provideelecttical-controlled means for automatically shifting the reflector orotherwise throwing the lig-ht out of its normal path and moreparticularly to provide electrical-controlltal means whereby when thecircuit is closed the reflector will be positively shifted in onedirection and will rcmain in this position until the circuit. is againclosed; to so construct and arrange the parts that upon the next closingof the circuit the reflector will be automatically shifted to its normalposition, thus avoiding; the necessity of maintaining the closed circuitto hold thc reflector in either position nl' adjustment.

bc in volition also resides in the partit-.tv lar construction ol' theshitting` mechanism and in such further details of construction as willmore fully hereinafter appear.

In the drawings: 4

Figure l is a horizontal sectional View through a lamp embodying: myinvention;

Fig. 2 is a vertical sectional view through the construction shown inFig. 1;

Fig. 3 is an enlarged side elevational View partly in section of theshifting` assembly;

Fig. 4 is an enlarged side elevational view of the shifting assembly, etright angies to Fig. 3.

Describing in detail the construction shown in the drawings, Adesignates the lamp casing, B the electric light bulb and C -thereflector in which the bulb is mounted to move with the reflector. Theopposite sides of the reflector are provided with pro jectinar pins Dand D which extend mio .bearings E and E on the inner face of thePatented July 9, 1918.

casingr A and form an axial pivot aboutl which the reflector C may berocked from the normal position shown in full lines in Fig. 2 to theposition shown in dotted lines in this figure.

For rocking;r the reflector' to its various positions there is employeda rock arm r rod F having one end pivotcd at I4" to .a lever Gr fixed toAthe pin D. The other end of the arm F pivotally connected at Fz to alever ti keyed to the shaft Il, the connection being such that as theshaft ll is rocked, it will througl'l the action ol" the lever G', therod F and the levi-r G, produce a corresponding rotation ot' the pin D'and thus rock the reflector about its axis.

While various constructions could be employed for rocking' the shalt [L1preferably utilize an elcctrical-coutrolled mechanism, the detailedconstruction and operation of which is as follows:

Secured to the shaft H is a pin T having its endsh l extendingn intoslots J and J2 in the yoke member J. The yoke member J in turn issecured by rivets J5 or other suitable means to the n'iovable plunger Kof the electro-magnet. rl`he current to the coils I.- of the magnet forenergizingI the stationary magnet L' controlled by a switch L`l in thecircuit L3. The arrangement is such that the closing,r of the circuitthrougl the switch will energize the electro-magnet,

draw the plunger down and rock the retieej,

tor, and l have provided novel moans uncreby the temporary closing nl'the ,cuit through the switch will at one time shitt the reflector fromits normal position and the next closing of the circuit willelectrically shift it hack to initial position.

In detail theniechanism for accomplishing this result comprises athrow-over device constructed and arranged is follows: Loosely sleevedon the shaft Il is a yoke M, to the outer end of which there is pivote-dat M an arm N, the latter at its rear end being secured to the casingthrough a spring N. Keyed or otherwise tixedly secured to the shaft Hinside of the yoke portion is an arm O which carries a transverse pinO', the'ends of which project into elongated slots Q in the yoke member'M. This slot and pin arrangement permits of sufficient lost motion toprovide a throwover mechanism whereby the arm O can be thrown overcenter bringn the pivoted end M of the arm N down be ow the shaft H sothat in its iosition, as show'T'Y--iin Figzilthe eprinr N wi l serre tohold the arm t) and haii-t H in the punition shown in Fig. 2.

However upon the elosimgr ot' the eireuit theiplunger K will be drawndownward carrying willi it the yoke J. whieh aeting upon the pin I, willrock the 4whalt ll so as to Parry the pivoted end M below the plane ofthe shaft ll and alloav the :spi-imgr to hohl the device in the positiondiown in Fig. Il. Upon the next closing of the switeh the plunger KbeineIr drawn downward will aet upon the oppo ite end ofthe pin -l androek the shaft ll in the reverse diref'tion. ln earh ease the pin andslot engagement and Q will eause the arm to tln'o\\'o\'er center andthu4 hold the refleetor in either position of adjustment until theeireuit is again elosed. This novel arrangement ol' parts avoids thenecessity of keeping the rilw'uit. elosed m order to hold the rellertorin itS adjusted position. 'I`l1e magnet, amat, he strong enough toovereome the tenxion of the Spring;` N', whieh spring also herve` tohold the reflector in either olits pimtions.

lt will be noted that the bull l is shifted with the reflector C, therebeing sullieient; plav permitted of the leading in wires l and R fromthe socket R2 so as not to interfere with the movement of the retleetor.Varou` ehanges in the partieular eonstruetion and arrangement ot' partsran he made without departing from the seope ot' my inventlon.
